Does Slick50 work?Are synthetic oils betterand are gas additives ok for the car. STPand stuff.?

Answer 1

Slick50 does NOT work. http://www.ftc.gov/opa/1996/07/slick.shtm

(neither does Duralube, Z-max, or many other products)

Synthetic oils are better, because they have smaller molecules, and those molecules do not stick to one another, and they bond with the metal, allowing for lower friction, Most motor oils also have friction modifiers, anti-foaming agents, and many other chemicals to help extend the life of the oil, and it's performance. Higher quality oils will use blends that they've proven to be most efficient.

I use fuel injector cleaner in my car, 1 bottle, for a full tank of gas, at each oil change - not sure if it's helping, but it's never hurt anything.

I wish you would mention what kind of car this is. Anyway, if it is an older car, chances are that you have at least some mild sludge and varnish build-up inside the engine. A good way to figure this out is to remove your oil filler cap and look at the back of it. Is it clean? Does it have brown powdery residue on it? Or Little hard cookie like deposits?? What ever you see on the back of the cap is what the whole inside of your engine will look like. You can use the best oils on the market, but it won't remove this junk. Adding slick 50 will only cover up the mess inside, as well. If the engine is new, or clean inside (also look as deeply as you can into the oil filler hole), then use a good synthetic oil. Slick 50 is OK, but sometimes it causes oil seal leaks. The best thing to do is to de-sludge your engine with butyl cellosolve, removing all old varnish, sludge, and deposits, then keep using a good synthetic, to keep the engine clean inside. Synthetic oils typically have more detergents and last longer and keep the engine running longer. Also, they continue to clean after you put it in. Marathon gasolines usually have a little STP already in it. Fuels like Mobil and Chevron and Texaco also have high detergency factors. Remember that a clean engine is a happy engine. Dirt is the killer!!

Additives are good for one thing...wasting your money. If you change your oil and do regularly scheduled maintenance you should not need any of these "cure-all's in a can".
